The bill will be presented soon after parliament returns next week, but the government lacks the numbers on the Senate to pass it without support from the Opposition or the array of crossbench Senators.

The Opposition wants to see the Omnibus Bill before deciding on whether it will support the move.

"The position we take in the parliament will reflect the position we took to the people in the election, but we have a process to go through. That typically begins with a careful examination of the legislation that is presented to us."

"The government has less than a stellar record when it comes to accurately representing Labor's views on these sorts of things."

The Finance Minister said the Coalition had already made 800 policy decisions since it won power in 2013 that he estimates will save the budget $221 billion over the next decade.
